Here are the apps plus one accessory that I use most often during my down time. I can't guarantee they are best in their class, but I can strongly recommend each one.
Keeping up with the news with your iPhone or iPad
If you have more than a handful of favorite Web pages, keeping up with new content can be a full time job. RSS (Really Simple Syndication) solves this problem. Websites use RSS to publish feeds, summaries of their latest content with links to the full Web page. Users subscribe to feeds by clicking on the standard RSS symbol.
RSS Reader applications aggregate all the feeds to which you have subscribed, periodically checking for updates. New articles can be read at your leisure. Readers can be Mac or Windows programs (like Safari and NetNewsWire), Web-based services like Google Reader, or iPhone or iPad apps like the five reviewed in this article.
All of the major news organizations have excellent and mostly free apps that let you access their websites. The advantage of these apps over visiting the sites using Safari is that they package the news to better fit the smaller screen. You don't have to scroll horizontally, and navigating between news categories is more efficient. In addition, they're quicker to load because they're not as graphically intensive as the full Web pages and include much less advertising. This also means that you're downloading less data to your device and making better use of the limited monthly allotments in AT&T's new data plans.
